An eQMS is a slightly odd system to validate. It is the system you use to manage validation, deviations and change control, so if it is not under control itself, everything recorded in it is open to question.
Here is a practical approach for teams moving to a new eQMS, especially a cloud one.
Classify it honestly
Most eQMS products are configurable off-the-shelf software, GAMP category 4. That is the right starting point for most of it. The trap is assuming everything is configuration. Custom workflows built with scripting, custom reports that feed decisions, and integrations with other systems may deserve more attention than the core product. Our piece on what GAMP over-categorisation costs explains why over-classifying the rest is just as costly.
Lean on the vendor, carefully
A good eQMS vendor will have validated its platform and should share the evidence. Use it. Re-testing standard functions the vendor already tested gains you little and costs a lot.
But read what they give you. Check that their testing covers the version you are buying and the functions you will rely on, and that their release process includes regression testing. A vendor summary that says validated with no evidence behind it is not something you can rely on. Our supplier qualification page covers how to assess them.
Test your configuration, not their software
Your effort belongs on what you configured. Workflow routing for each record type. Who can approve what. Required fields and signature meanings. Due date and escalation rules. Effective dating of documents, so the right version is in force on the right day.
The most common failure is approval routing that works for the standard path and breaks when someone is absent, a record is reassigned or a step is rejected. Test those paths.
Migrating legacy records
Moving existing deviations, CAPAs and documents is often the riskiest part of the project. Decide early what moves as live records, what moves as read-only history, and what stays archived in the old system. Then verify the migration: counts reconciled, a sample checked field by field, attachments opened, and history preserved. Our guide to data migration validation goes into this in detail.
Electronic signatures and records
An eQMS is full of signatures: document approvals, deviation closures, CAPA effectiveness checks, training acknowledgements. Each one needs to meet Part 11 and Annex 11 expectations in practice, not just in the vendor brochure.
Check that each signature shows the signer's name, the date and time, and what the signature means, such as reviewed or approved. Check that signatures are linked to their records so they cannot be copied or moved. And check that a record cannot be changed after approval without the change being visible and the approval reconsidered. These are standard functions, but the meaning of each signature is your configuration, and it is often left at the default.
Releases you do not control
With a cloud eQMS, the vendor upgrades on its own schedule, often several times a year. You need a routine for that: read the release notes, decide what affects your configuration, test those parts in a sandbox before the change reaches production, and record the decision. Done well, this takes days, not weeks. Done badly, it means either constant revalidation or none. Our cloud & SaaS validation and eQMS implementation pages cover this in more depth.
